7-5. Calculate the 95% confidence interval for each set of data in Problem 7-4 if s is a good
estimate of o and has a value of: *set A, 0.20; set B, 0.070; *set C, 0.0090, set D, 0.30,
*set E, 0.15; set F, 0.015.
7-6. The last result in each set of data in Problem 7-4 may be an outlier. Apply Q test (95%
confidence level) to determine whether or not there is a statistical basis for rejection.
